REFRIGERATOR-CAR CONSTRUCTION'.

- Application ld' January 6, 1925. Serial No. 904.

In the drawings:

Fi 1 is a partial horizontal section of a car body constructed in accordance with this invention; I

Fig. 2 is a transverse vertical section taken on the line 2-2 of Fig. 1;

Fig. 3 is a fragmentary sectional vievvl drawn to a larger sca-le and taken at one of the side posts shown in Fig. 1; y

Fig. 4 is a perspective view of a section of the insulated side wall of Fig. 1 shown detached from the car body;

Fig. 5 is a perspective view of one of the removable key posts shown in Fig. 1; and

Figs. 6 and 7 are horizontal sections `taken through 'side posts and showing key posts and Wall sections of modified constructions.

In the making ofl repairs to damaged car side walls it is frequently necessary to remove the entire side of the lcar from the doorpost to the adjacent corner post in order tomake a proper repair to a particu'- lar part of the side Wall and in the case of insulated or refrigerator cars this necessitates the removal and replacing of the insulation also. A car side Wall built of sections Which could be removed independently for repair or replacement Would greatly reduce the amount of the side wall that must be removed in order to repair any particular part and would greatly expedite the making of such repairs. A further advantage would be obtained in the making and repairing of the sections as the Work could be done more expeditiously and better when done at a bench than when done in position on the car. v

Itis an object of this invention to provide .an improved wall construction for cars, and more particularly to provide an improved Wall construction for insulated or refrigerator cars comprising Wall sections which may be applied as units-and which will permit of a single unit being repaired or replaced without necessitating removal or reconstruction of the adjacent sections. It is also an object of this invention to provide a means by which the sections may be readily and vsecurely held in position and which Will permit of ready removal for repair and replacement'. n

In the drawings the invention is shown'as applied to a refr'gerator car having 1nsulated walls, although. it may be applied to cars of other description. rlllie car shown comprises an underfraine 1 having holsters 2, cross bearers 3 and side sills 4 of. any desired construction. To the underframe are secured the side posts 5 which carry the construction. Tov the outsides of the nailing strips 8 are secured the lbottom courses 12 of the side sheathing which lie between the side posts 5 and the nailing strips 8.

. To the side plates 6 are secured an insulated ceiling 14 and a roof 16 of any desired cony struction. It Will be noted that the ioor 10 and the nailing strips 8` provide a continuous iat surface extending to the bottom courses 12 of the side sheathing and that the ceiling 414 provides a fiat surface extending to the side plates 6, both the floor and the ceiling extending to the ends of the car. At the ends of the car the floor and ceiling are joined by insulated end'walls 18 which are built in the usual manner and at their sides are joined to end sections 20 of the sidewalls whichv are also constructed in the usual manner and which extend from the end posts 22 to the adjacent side posts.

Fromthe side posts 5 adjacent to the ends of the car to the posts forming the door openings (not shown), the side walls are formed of independently fabricated sections 24 which extend between adjacent side posts 5 and from the iioor 10 tothe ceiling 14,

the sections being secured to the side fposts 5 by key posts 26 of insulating material and preferably of Wood. As shown in Figs.,

2, 3 and 4, the sect-ions 24 comprise a rectangular frame 27 of insulating material and preferably of wood havin vertical vmembers 28 and horizontal mem ers .30 to which are secured layers 31 of a suitable insulating material between which is'placed insulating packing of any suitable material, shown in Fig. 3 as comprising two layers 32 of a material such as hair felt. To the frame 27 and overlying the insulating layers 31 are secured the outer sheathing 34 and the inner lining 35, both the outer sheathin 34 and the inner lining 35 are shown forme of Wood strips though other suitable material may be used. The outersheathing, at the top, and the layers of. insulation and inner lining are finished Hush with the horizontal members 30 of the frame 27, while the outer sheathing 34 and adjacent layer` l parts of the wall section along the Vertical edges of the same provides shoulders'which are engaged'by shoulders formed on a comple'mentary shaped wood 'key post 26 whicl1 1s secured to the side posts 5 by bolts 36.-

In the modied construction shown 1n jFig. 6, the wall sections 'are shown as comprlsing the outer sheathing 34 and innen lining 35 secured to a frame v27 and conlining between them an insulation 40.-` Thevertical members 28 .of theframe are set Vback slightly from the vertical edges ofthe outer sheathing' 34 and project slightly beyond the vertical edges of the inner lining 35 and are tapered to be engaged by a comlementary formed wood' key post 41 which lias -faces engaging with the shoulders formedv along the vertical edges of the wall sections and inclined faces engaging with the inclined faces of the vertical frame members 28. In this construction, the, key ost 41 is formed of a tapered member 42 w iich receives the bolt 43 bywhich lit is secured to v the side ost 5, andastrip 44 issecured to the me er 42 byv screws the heads of the bolts 43. y

In the modified construction shown .in Fig. 7, the wall sections com rise the outer A45 and covering are secured to the. frame 2 and between' vwhich are confined the insulation 50 and 51. In this construction the vertical members 28 of the'frame are shaped to-receive the channel-shaped -key vpost 53 'having iianges 54 which are securedfto the frame members`28 by screws 55 Whichpa'lso secure cover strips'56 and` insulation 57 to the key posts, the key postsfbeinlg secured to the side posts b the bolts 58. n this construction, as in tlleother constructions, shoulders or inclined faces are formed along the vertical edges of the wall sections which are engaged by the ke posts so that `the wall sections are secure y held to the sidel posts by the ke posts. 1 i A n constructin a car in accordance with this invention, t e car frame floor 10, ceiling 14 end wall 18 and end. sections 20 of vthe-side walls are constructed in theusual manner, except that the endsof the sections 20 adjacent the side posts 5 ,are fashioned to be en aged by the key posts 26, Sections 24 are t en placed in position against thel inner faces of side posts 5 with the lower edges of the vbottom courses of the outer sheathingon the sections 24 engaging withl the upper edges of thelower course 12 of l the side sheathing. It will be noted that the meeting edges of the sheathing courses 12": and 60 are beveled to maken tight joint of the car.-

` .said fixed sheathing 34 and the inner l1ning-35 which 'from the inside ofthe car.l

. the inner faces of said detachably secured to said fixed posts' and i and that the upper courses 61 of the sheathlng are z aind out to receive the side plates '6. The ey posts are fthen placed in posikeyv1 posts. e o lreplace a section, the key posts at opthe case of the modifications 7nv posite'sldes' of the section to be replaced `are 75- released from the side post-s and withdrawn to the inside of the car, whereupon the section between these posts is free tov be 're'- moved to the inside of the car and 'replaced bylan'other section which is inserted in posi- 80 tion against the side posts 5 from the inside What is claimed is: 4 1.
